Abstract : This thesis examines the effect of public policies on the functioning of competitive markets. It addresses one issue of competition policy and one issue of sectoral regulation. The first part of the thesis focuses on merger control: it first examines the effects of mergers on the prices of goods, and then the decision of the competition authority is endogenised. The first article examines whether one of the objectives justifying the existence of competition policy - the enhancement of consumer surplus - is achieved in practice for merger control. Using French multi-sectoral data, the effects of mergers on the prices of goods and services in the relevant sectors is estimated. In a second article, the decision of the competition authority is examined through an empirical analysis of the determinants of the opinions of the French Competition Council on mergers. The second part of this thesis deals with a regulation question: how restrictions on free entry are valued by the actors on the market, because of the anticipated profits. The determinants of this value are then estimated. This question is addressed in two situations: first, the value of the so called "digital dividend", which corresponds to the spectrum released by the extinction of analogue broadcasting of television, then the value of a taxi license. The elasticity of the licence value to the number of granted licenses is estimated.
